My boss fired his secretary shortly after hiring her. She always showed up late, she chatted on her cell phone, and she worked very slowly. He had every reason to let her go.
She accused him of gender discrimination. She even hired a lawyer, and my boss received a summons to appear in court.
During the initial hearing, the judge could tell that she was the kind of complainant who just wanted to cause trouble. Once my boss showed evidence of her sloppy work and tardiness on her time card, the case was thrown out and he was free to go. She received a hefty fine for wasting everyone’s time.
